preconceived opinion

It remains imperative that bias does not prevent us from accepting results that do not support our preconceived opinions.

The problem is that people tend to interpret disasters, and most other things in life, in a way that validates their preconceived opinions.

I tried to banish every preconceived opinion of Matthew Morrison playing the Grinch from my mind before flipping to “Dr. Seuss’ The Grinch Musical!” on NBC on Wednesday night.

He said that it was important for a jury or judge not to have “preconceived opinions” about the guilt or innocence of those charged.

Sometimes, in politics as in science, factual analysis does not support preconceived opinions.
